1998 Volkswagen Cabrio
So I bought this car a couple months ago
and the check engine light came on and I
had the code ran and it said mass air flow
sensor so I replaced it. It came on again a
few days later and it says it's the same
thing. All they say it to have it reset again
but I've done that twice now and it doesn't
seem to be working. What could this be? I
don't know anything about cars so I have
absolutely no idea what to do.
